It was more on the service side - i think his experience with sales was fine aside form the sales folks not even understanding how all of the systems actually worked. But many things. So his trailer had an initial leak of the window seal from being a brand new trailer. The shop, instead of removing the window and replacing the butyl tape like you should, just calked some silicone over the top of it. His main slideout, when fully out, left a 2" gap at the top, striaght from the factory. It took the shop several weeks to understand that was even a problem - at first they told my dad that is normal, which it is not... After forcing the issue, they finally adjusted the slide, so that the seal, when fully out, was actually sealing. They also were not even sure how the solar from the factory worked, or what the battery disconnect actually did - so my dad had to call and have a long conversation with the factory, who also couldn't seem to explain or provide a wiring diagram. So he reverted again to have the shop spend several hours with a DVM testing wires to see how it was actualy wired and what did what and when. Which is super poor quality for a 'high quality' company. Recently, my dad was simply going to have his trailer winterized and maintained. Apparently, over a week later the shop didn't even know they had his trailer and totally forgot. So they rushed the process in one day and now the concern of if they even did winterize, or pack wheel bearings, is in question. Additionally, I can't remember the details, but one aspect of a standard winterizing was not even completed - i think it might have been draining the water heater? So clearly they didn't even do the job he paid for. Needless to say he has zero trust in them now and is worried for when he actually has a legit problem that he cant fix himself. - and at almost $80,000...these things are just not acceptable.
But this is not an abnormality. One of the RV dealers in Tacoma, where I got my little trailer, I had to do a warranty repair on the hot water heater. They removed the entire heater, which was not necessary, and left it outside, with a gaping hole over a weekend apparently. WHen I got it back, there was rat $&^! and piss everywhere... This is my full time home, so, I spent many hours sanitizing everything, washing dishes, cleaning seats, etc... WHen I went to the dealer to talk with the manager, his response - oh well sometimes that happens. Even though you know rats carry disease. And yes, I'm a tad bitter ha. Its difficult to trust people these days it seems.
I would like to hope that incidence is just relating to my dad, who can be a pushover sometimes and not stand up for what is wrong. But, it seems to be a pretty consistent theme these days. So I would say, what you can do yourself, do. And select carefully what you have others do. Sad to say....
